SPOKE-TENONING MACHINE.

SPECIFICATION forming part of Letters Patent No. 262,107, dated August 1, 1852.

Application filed May 1, 1882.

To all whom it may concern:

Beit known that I, HILAIRE FARE, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Spoke-Tenoning Machines; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view; Fig. 2, a front end view; Fig. 3, a longitudinal section through the cutter-head.

This invention relates to an improvementin apparatus for cutting the tenon on the end of spokes of wheels. The spokes are first driven into the hub. Then the hubis placed upon a center, so as to revolve in a horizontal plane and present the spokes successively to the tenoncutting device, the tenon-cutter being usually whatistermed ahollowauger. Itisdesirable to cut the tenon concentric with the axial line of the spokethatis, upon the same center on which the spoke is turned; but in the usual construction of spoke-turning machines the hollow auger cuts directly onto the spoke with out any special guide or centering of the spoke.

The object of myiuvention is to construct a machine for a centering device within the hollow auger,combined with mechanism foradjusting the centering device and feeding the auger onto the spoke; and in such a machine my invention consists, as more fully hereinafter described, and particularly recited in the claims.

A is the bench or support upon which the machine is placed. The machine consists of a post, B, fitted into a socket in the bench, and carrying at its top atransverse sleeve, C,which 40 forms a bearing for the driving-shaft D, and so that while the shaft may be revolved freely in the hearing it may also be moved longitudinally therein, asindicated in broken lines ,Fig.

1. The shaft D is provided with a crank, E, 5 or other suitable device for imparting rotation thereto either by hand or power. At the opposite end of the shaft to where the power is applied an arm, F, is arranged, through which the shaft extends, so as to revolve freely there- (No model.)

in. A pinion, G, outside anda collar, H, inside the arm on the shaft carry the arm F with the shaft in its movement back and forth in its bearing C. In the lower end of the arm F a cutter-head,L,is supported, asseen in Fig.3. This cutter-head is substantially like the commen and well-known hollow auger. It is pro-' vided with a cutter, a, and is arranged to revolve in its bearing in thearm F. Power for revolving it is communicated through the pinion G on the shaft D, working in a corresponding pinion, P, on the bodyRof the cutter head, and

is attached to the arm so as to move with itin its longitudinal movement, as seen in Fig. 3. Longitudinally through the cutter-head and through the post B is a mandrel, S, screwed thereto through the post, as seen in Fig. 3,and provided with a hand wheel or crank, T, by which it may be turned by hand. This mandrel is concentric with the cutter-head. Its outer end terminates in a center, I), so as to engage the center-point in the end of the spoke,

as shown in Fig. 3. U is a hand-lever hung to the post, as at d, and connected by a link,

6, with the arm F, so that the workman, taking hold of the hand-lever, may move the cutterhead forward and back-that is, onto and off from the spoke.

The hub with the spokes therein is arranged relatively tothe cutting mechanism in the usual manner, and so that the path of the spokes, as the hub is revolved, Will pass the center of the cutter and come in line with the mandrel S. When the first spoke is presented in front of the mandrel the operator turns the mandrel forward to bring the center into connection 8 5 with the spoke, and so as to firmly hold it, in its proper axial line. Then the revolving cutter is advanced to out onto the spoke and form the tenon in the usual manner. The tenonfinished, the cutter is withdrawn as well as the 0 mandrel, then a second spoke presented, and the tenon cut as before, and so on until all are out.

To automatically feed the cutter during the cutting operation, a bell-crank lever, fg, is ar- 5 ranged, the arm g bearing against the cutterhead of arm F, as seen in Fig. 1. To the other arm,f, a weight, h, (or may be a spring,)is applied, which will press the cutter forward during the cutting operation.

Instead of working the mandrel by means of a screw, it may be provided with a spring, 71, within the cutter-head, bearing at the forward end against a collar, 1, on the mandrel and at the rear end against a shoulder, m, in the cutter-head, and so that the tendency of the spring is to force the mandrel outward and hold it in contact or connection with the spoke. In this case the same handle U will withdraw first the cutter-head and then the mandrel, and when moved forward for the second spoke the man drel will, by means of the spring, be first engaged with the spoke, and then the cutterhead will be advanced against the spring; or the spring may be arranged as described and the mandrel screw-threaded, as before described, and asshownin Fig. 3. The spring in that case will serve to withdraw the cutter-head and the hand-lever used to advance it.

I claim- 1. The combination of the shaft D,arranged for free revolution and longitudinal movement in its bearing 0, the arm F thereon, carrying the cutter-head 1% below and in line parallel with the shaft D, pinions connecting the shalt D and the cutter-head, and the centering-mandrel S, arranged longitudinally through the cutter-head, substantially as described.

2. The combination of the shaft D, arranged for free revolution and longitudinal movement in its bearing (J, the arm F thereon, carrying the cutter-head 11 below and in line parallel with the shaft D, pinions connecting the shal't D and the cutter-head, and the centering-mandrel b, arranged longitudinally through the cutter-head, with the handlever Tl, connected to the arm which carries the cutter-head, substantially as described.
